What method is used to destroy contaminated disposable items completely by fire?

The method used to destroy contaminated disposable items completely by fire is known as incineration. This process involves subjecting the waste to high temperatures in a controlled environment, ensuring complete combustion and reducing the waste to ash, gases, and heat. Incineration effectively eliminates pathogens and hazardous materials, minimizing the risk of environmental contamination. It is commonly used in medical facilities for the safe disposal of infectious waste.
